....process, or not. Here we concentrate on two notions of quantum capacity, one investigated for example in [48] 51] 50] 60] and concerned with the maximum size of a Hilbert space all of whose pure states can be preserved with high fidelity, and another arising for example in [16] 17] [61], 19] concerned with the maximum entropy of a density operator whose entanglement with a reference system which does not undergo the noise process can be preserved with high fidelity. This chapter shows that these two definitions of capacity are in fact equivalent, in the situation in which ....

....Coding Theory. The qubit can be defined in quantum information theory as the amount of information that can be carried in a quantum system with two basis states, e.g. the internal degree of freedom of a polarized photon. The qubit is thus fundamental unit of quantum channel capacity. Nielsen [Nie96] Svozil [Svo95,Svo96] Holevo [Hol97] Knill, Laflamme [KL96a, KL96b] Ohya [Ohy98] develop a theory of quantum error correcting codes and quantum information theory) e.g. they give the definition of quantum mutual entropy for an entangled state.
